I believe that's an awesome idea, i would totally join one of them, but what about player's making their own guilds?Chat is simple enough to hold some *faction name here - Copherfield: message here* thingy

Something like Factions plugin (not exactly it since it messes up with residences i believe) where you can get your friends to be part of your clan and idk, give themselfs a tittle?

I like the idea's of guilds, maybe even trading between guilds because the woodcutting guild would have massive amounts of wood (since thats what they dedicate themselves too) and the brewing guild has potions they could trade some logs for potions it would be cool.

EDIT: Also brewing guild would be dependent on hunting guild for gunpowder spiders eyes and such while the hunters would need heal potions

Clans go tons of ways for E.X. Social, PVP, Rule Enforcers, and so on. Its up to you how you want the clans topic to be. As factions on the server, how is that suppose to work? Possibly in the Wilderness?
